This Thesvin washable vacuum cleaner filter is a disc-shaped filter element that captures fine dust, allergens and PM2.5 particles before air leaves the dust cup. It fits handheld vacuums, robot vacuums, mite removers, wet-dry cleaners and compact car vacuums, and is made for OEM and ODM programmes that need a repeatable dimensional match. It is designed for buyers and engineers who care about how the filter seats in the housing, how the frame seals, and how the airflow path stays open.
Fitment starts with the frame. We mould the outer frame to your drawing or sample in engineering plastics, with round, flat or special profiles available. A rubber sealing ring can be added around the rim so the filter seats against the housing with a tight, repeatable seal. The result is a part that locates positively in the dust cup, does not rock in service, and keeps unfiltered air from bypassing the media.
Because every host device has its own cavity depth, centre bore and retaining method, we do not force a catalogue size onto your product. Instead we match the disc diameter, overall thickness, centre hole, pleat count or media area, frame colour and logo to your 3D data or returned original part. All structural dimensions are built to your specification, so the filter drops into the existing housing without tooling changes on your line.
The interface also matters for service. A disc filter is usually removed by hand, washed and refitted, so the frame edges are kept clean and the seal is designed to survive repeated removal. We confirm the fit on samples before mass production.
The media is a high-precision PTFE microporous membrane, a composite PP melt-blown layer, or an antimicrobial treated filter paper, selected to suit the particle load and wash cycle of your application. The filter catches PM2.5, fine dust, dust mites, pollen and pet dander inside the dust cup, which helps prevent exhaust air from carrying fine particles back into the room.
Airflow is a design parameter, not an afterthought. The media uses a high-porosity, breathable structure so operating resistance stays low. That protects motor suction, reduces the risk of motor overheating and helps maintain battery run time. For buyers comparing filter options, the trade-off between efficiency and pressure drop is tested on our CNAS-recognised lab equipment, and the data can be supplied with the sample.

Thesvin has been developing and manufacturing filtration products for more than 20 years and has exported to Europe, the United States, Japan and Korea for over 20 years. Ourquality system is built around IATF 16949, which we obtained in 2024, together with ISO 9001, ISO 14001 and ISO 45001. Dimensional consistency is controlled through IQC, IPQC and OQC stages, so the frame, seal and media geometry stay within tolerance from lot to lot.
Our own laboratory is CNAS-recognised and can issue reports on filtration efficiency, dust holding capacity and resistance. The production base covers 50,000 m², including six clean workshops totalling 20,000 m². Products meet REACH and RoHS requirements and compliance documents can be provided. Multiple automated lines support monthly capacity in the millions of pieces, and we have developed more than 1,000 filtration solutions for OEM and ODM customers. We are located in Zhongshan, Guangdong, China.
To quote accurately, send us the device or vehicle model, the filter size or a drawing, the airflow or water flow requirement, the operating conditions (dust type, wash frequency, temperature) and the quantity you expect. If you do not have a drawing, an old part is enough to start. Contact us through our contact page and our team will confirm the fitment route and sample plan.
Fitment is confirmed against your drawing, 3D file or the original filter, not against a generic size. We mould the frame and rubber seal to your housing dimensions, so the disc seats and seals correctly. Send the housing opening, disc diameter and thickness and we will check the interface before quoting.
Yes. A returned original filter is enough for us to measure the diameter, thickness, centre bore, pleat count and seal profile. We then build a sample to match the host device. Where needed, we can also work from a 3D scan of the old part.
The media captures PM2.5, fine dust, dust mites, pollen and pet dander, and efficiency depends on the grade selected. Our CNAS-recognised laboratory tests efficiency, dust holding capacity and resistance, and reports can be supplied with the sample. We confirm the target efficiency against your airflow and pressure-drop budget.
Wash life depends on the media and cleaning method, so we validate it on the sample rather than quoting a single figure for all versions. PTFE and composite PP media are chosen for repeat washing in handheld and robot vacuum service. Tell us your expected wash frequency and we will recommend the appropriate grade.
Yes. We customise the frame shape (round, flat or special), frame colour, rubber sealing ring, filter media grade, logo and retail packaging. All structural dimensions are built to your device specification. This is an OEM and ODM service, and we have developed more than 1,000 filtration solutions.
MOQ and lead time are set per product and are confirmed with your quotation, because they depend on the frame, media and order quantity. We support sample validation before mass production. Please include your expected quantity in the inquiry so we can give a firm schedule.
Yes. Send the device model, size or drawing, airflow requirement, operating conditions and quantity through our contact page. We will review the fitment and return a sample plan and quotation. Test data from our CNAS-recognised laboratory can accompany the sample.
Replacement interval follows the dust load, wash frequency and the media grade you select, so we do not apply one interval to every application. As a guide, a washable disc filter is cleaned regularly and replaced when airflow drops or the media shows damage. We can advise a service interval for your specific device during sample validation.
